	<h2>AutoComplete: Remote Data via DataSource</h2>

	<div id="example" class="promo">
	<div class="example-intro">
	<p>
This example demonstrates how to provide autocomplete suggestions using a <a href="http://developer.yahoo.com/yui/3/datasource/">DataSource</a> instance. While AutoComplete supports a variety of result sources without requiring a DataSource, using a DataSource can give you more control over how results are retrieved and processed, and also allows you to share data with other DataSource-based widgets on the page.
</p>

<p>
Type the name of a band or musician to see results from <a href="http://music.yahoo.com/">Yahoo! Music</a>. Can't think of one? Try some of my favorites: Dandy Warhols, Black Rebel Motorcycle Club, The Morning After Girls, Dr. Theopolis, or Echo &amp; the Bunnymen.
